Personas

Calaway's character has two alternate identities. The one most commonly associated with the Undertaker is "The Deadman:" a ghoulish, morbid priest-like figure. The second persona is the "American Bad-Ass" which emerged in the early 2000s. Calaway would dress up in outlaw motorcycle attire and drive to the ring on his motorcycle.
